Predicted to enable aspartic-type endopeptidase activity; identical protein binding activity; and ubiquitin binding activity. Predicted to be involved in several processes, including cellular response to hydroxyurea; proteolysis; and regulation of DNA stability. Predicted to be located in cytosol and nucleoplasm. Orthologous to several human genes including DDI2 (DNA damage inducible 1 homolog 2). [provided by Alliance of Genome Resources, Apr 2022]
